>             Project: Ignite
>          Issue Type: Sub-task
>          Components: hadoop
>    Affects Versions: 1.7
>            Reporter: Vladimir Ozerov

>             Fix For: 1.8

>
> In new arhitecture {{IgniteHadoopIgfsSecondaryFileSystem}} should load dependent classes
using {{HadoopClassLoader}}. We need to guarantee it.
> Proposed solution:
> 1) Separate {{HadoopClassLoader}} is initialized for the file system on start ({{ctor}}
or {{start}} method);
> 2) All interfaces methods are wrapped into {{HadoopUtils.setContextClassLoader}}
> 3) start/stop methods are wrapped as well.
